SPECIFICATION forming part of Letters .Patent No. 713,829, dated November 18, 1902.

Application led October 9,1901. Serial No. 78.085. (No model.)

all whom t may concern:

Be it known that I, ERNEST E. YAXLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Telephones, of which the following is a specification.

My invention relates to what are known as wall-telephones. Awall-telephoneusually to consists of a back adapted to be screwed or otherwise attached to a wall and adapted to afford a support for the usual electrical devices-such, for example, as the transmitter, receiver, bell, condenser, lightning-arrester, and inductioncoil.

The objects of my invention are to provide a wall-telephone of a simple, compact, and efficient construction, to provide a construe tion and arrangement tending to reduce the 2o thickness of the back, to arrange and dispose the various parts in such manner as to render each of the various electrical devices readily accessible, and to provide certain details and features of improvement tending to reduce the cost of manufacture and to render a device of this character efficient and serviceable.

To the foregoing and other useful ends the back or back board of my improved wallgo telephone is preferably composed of two flat orsubstantially flat sections which are hinged together at their side edges and adapted to lie liatwise together, so as to provide a dat and comparatively thinback or back board for the 55 telephone. The flat and comparatively thin back board thus provided is adapted to be secured or attached to a wall in the usual manner. To this back board are attached the various electrical devices, such as the 4o transmitter, receiver, condenser, lightningarrester, and theinduction-coil. Preferably one of said back-board sections is recessed or llollowed out from top to bottom or substantially for its full length, so as to provide between the two sections a chamber for the condenser, lightning-arrester, and the magnets for the bell. The outer of said sections is preferably adapted to support the bell, transmitter, induction-coil, andthe receiver and 5o receiver hook or lever. The condenser and lightning-arrester are preferably mounted in the said recess formed in the other section. The magnets for the bell are preferably arranged in a recess formed in the upper portion of the outer back-board section. This outer back-board section is, as stated, hinged to the other section, and when closed together the two flat sections constitute a flat and comparatively thin back for the telephone. The recessed formation of the two back-board 6o sections permits of a desirable and advantageous disposition of the bell, lightningarrester, and condenser and permits these three devices to be arranged in such manner as to be readily accessible. sections are closed together, the be1l-mag nets occupy a position at the top of the chamber which extends, as stated, substantially from top to bottom of the telephone back board. The condenser, which is preferably 7o flat and comparatively thin, occupies the lower portion of 'the chamber formed by the recess in the back member or section of the telephone back board, and the lightning-arrester occupies a position between the bellmagnets and the condenser. The transmitter is secured in any suitable manner to the outer back-board section. The induction coil and the receiver hook or lever can be located and arranged so as to be readily ucces- 8o sible in a box or inclosure constructed so as to project outwardly from the lower portion of the outer back-board section. Preferably the top or lid of this box or inelosure is hinged at its back edge to the back board, and the front or forward wall of this box orinclosure is preferably removable for the purpose of giving greater access to the receiver-hook and the induction-coil. The nature and advantages of my invention will, however, herein 9o after more fully appear.

In the accompanying drawings, Figure l is a perspective of a wall-telephone constructed in accordance with my invention. Fig. 2

is a persective of a wall-telephone shown in Fig. l, the two bacleboard sections in this case, however, being opened or thrown apart, so as to expose the interior and show the arrangement and disposition of the various electrical devices. Fig. 3 is a horizontal section roo I/Vhen the two 65 the box or inclosure for the receiver-hook ando induction-coil being shown in side elevation. Fig. 5 is a cross-section on line 5 5 of Fig. 4, showing the arrangement of the inductioncoil and receiver hook or lever and also sh owing the manner in which the front or forward wall of thebox or inclosure is made removable.

As thus illustrated, myinvention comprises a back or back board A, which, it will be observed, is of greater length than width and which is fiat or substantially flat and comparatively thin. This back board is preferably composed of two flat boards or sections adapted to lie fiatwise together. The section a is adapted to be screwed or otherwise fastened to the wall. The outer fiat section a' is preferably provided with hinges Z, which connect it with the inner or back section ct. In this way the two fiat sections are hinged together at 'theirside edges and, as stated, are adapted to lie flatwise together, so as to providea flat and comparatively thin back board for the telephone.

In order to provide a suitable chamber for certain of the various electrical devices usually comprised in a telephone of this character, the inner or back section d is preferably recessed or hollowed out for substantially its full length. This recess, as shown in Figs. 2 and 4, is of such height as to extend substantially from the top to the bottom of the back board and is of such depth and character as to provide between the two sections a comparatively thin chamber for containing, in this case, the condenser, lightning-arrester, and bell-magnets. Preferably the outer section a is provided with a recess'or opening a2, which, it will be observed, extends entirely through the section. The recess d3 in the inner or back section does not, it will be observed, extend entirely through the section. In this way the inner or back section ctis so formed as to have a relatively thin back wall co4. The outer section ct forms the front or outer wall of the recess or chamber a3. The recess or opening a2 is designed to coperate with the upper portion of the recess a3 in accommodating the bell-magnets. These bell-magnets B are preferably secured to a bar a5, which is in turn preferably secured to a relatively thin plate as. This plate d6 is secured to the outer surface or the front of the back-board section ct and is adapted to cover the opening a?. It will be readily understood that the bell and the bell-magnets B can be of any suitable known or approved form. The transmitter C can also be of any suitable or approved form and may be provided with an arm c, having a swinging connection with the bracketplate c', which latter is preferably secured to the plate a6.

When closed together, the two sections of the back board provide, as stated, a comparatively shallow chamber a3, and the conden-ser D is therefore preferably flat and comparatively thin and is, as shown in Figs. 2 and 4, adapted to fit within the lower portion of said chamber or recess a3. This condenser may be of any suitable or desired form. The lightning-arrester E is preferably and desirably located vbetween the condenser and the bellmagnets. It will be readily understood that this lightning-arrester can be of any suitable and approved form. When thrown apart, as 'shown in Fig. 2, these three electrical devices-that is to say, the bell-magnets B, the condenser D, and the lightuingarrester E- are all accessible and so located and arranged as to be readily and easily detached or removed from the telephone back board. At this juncture it will be observed by reference to Fig. 2 that one of the electrical connections is made through the upper hinge Z, and also that certain other electrical connections are made through the coil-springs 2 and 3. It will be observed that these springs have their opposite ends attached respectively to the front and back sections of the telephone back board A. These springs provide exible or extensible electrical connections which permit free swinging or relative movement between the two back-board sections. When the outer section is swung back and closed, the coil-springs 2 and 3 occupy the recess 4,formed in the section a of the telephone back board. It will be seen that this recess 4 is arranged at one side of the condenser D. In this way this supplemental recess 4 serves to protect the coil-springs 2 and 3 against injury in closing the outer back-board section.

The receiver hook or lever F, which is adapted to support the usual receiver G, is arranged to project from the side of the box or inclosure H, which latter is constructed to project from the lower portion of the outer back-board section ct'. It will also be observed at this juncture that this box or inclosure is adapted to contain an inductioncoil I. It will be readily understood that this induction-coil, and also the receiver hook or lever, can be of any suitable or desired form of construction. With respect to the arrangement or disposition of these two devices, however, the receiver hook or lever F is preferably arranged between the induction-coil and the front or outer wall of box or. inclosure. The top or lid 7i, of this box or inclosure is preferably provided with hinges h', which connect with the front or forward section of the telephone back board A. In this way the top or lid can be raised to permit access to the induction-coil and receiver-hook, and in order to render these devices further accessible the front or forward wall h2 of this box or inclosure is made removable. This removable front wall of the box or inclosure is preferably comparatively thinand adapted to rest in grooves or channels h3, formed on the inner surfaces of the side walls h4. With this arrangement the lid 71, can be lifted up, and

by then lifting or pulling out the wall h2 IIO ready and convenient access may be had to the interior of the box or inclosure ll.

It will be seen that by my in ven tion l provide a wall-telephone having a flat and comparatively thin back board and that the construction, although simple and compact, renders the various electrical devices unusally accessible.
